The Department of Environmental Protection has extended the expiration of the current NPDES Phase II MS4 general permit (PAG-13) by one year from midnight, March 9, 2009 to midnight, March 9, 2010.

DEP also is extending all existing MS4 PAG-13 general permit approvals, waivers from permit application requirements and exemptions from the MS4 operator designation scheduled to expire.

Existing MS4s are authorized to continue to discharge stormwater in accordance with the terms and conditions of the authorized permit and to comply with MS4 permit requirements. Included in this extension is the requirement to continue implementation of the existing program and to provide annual reports on the progress of program implementation.

If you are using an NPDES Phase II MS4 individual permit, you must either submit an application for a renewal permit or request an extension of your current permit 180 days or more before the expiration of your current permit.

The form for an extension of the individual permit is available online.

The existing PAG-13 permit documents will continue to be available from DEP Regional Offices. In addition, the permit documents are on file at the Department of Environmental Protection, Bureau of Watershed Management, 10th Floor, Rachel Carson State Office Building, 400 Market Street, Harrisburg, PA 17101.

DEP published a formal notice to the effect in the Pennsylvania Bulletin on August 23.
